Answer:
It says energy can't be created or destroyed
Explanation:
The Force per meter on a straight wire carrying current in a magnetic field is<u> 0.045 N/m.</u>
<u>Calculation:-</u>
F/ℓ = B I sin θ
Where B – Magnetic field = 0.02 T I – Current = 5 A
Substituting the values
F/ℓ = (0.02) (5) (sin 27 deg)
F/ℓ = <u>0.045 N/m</u>
A force is an influence that can alternate the motion of an item. A force can cause an item with mass to trade its pace, i.e., to boost up. force can also be described intuitively as a push or a pull. A pressure has both value and course, making it a vector quantity.
The push or pull on an item with mass causes it to change its velocity. force is an external agent capable of converting a frame's nation of relaxation or motion. It has significance and a path. A force is a push or pulls among gadgets. it is called an interplay because if one object acts on some other, its movement is matched with the aid of a reaction from the alternative object.

Answer:
15 N
Explanation:
According to Newton's third law of motion, to every action, there is an equal and opposite reaction. This reaction is equal in magnitude to the force acting but in an opposite direction.
Now, if the book weighs 15 N, an opposite equal force will be: N = -15 N
But the magnitude of this will be the absolute value which is 15N.
Given:
u(initial velocity)=0
a=5.54m/s^2
v(final velocity)=2 m/s
v=u +at
Where v is the final velocity.
u is the initial velocity
a is the acceleration.
t is the time
2=0+5.54t
t=2/5.54
t=0.36 sec
The surrounding environment cool off is the answer
